Module Installation

Modules must be mounted on a DIN rail.

1. Allow sufficient finger clearance for opening PNS door.

2. Allow adequate clearance for communications port cables.

3. Allow adequate space for power wiring.

The PNS with power supply attached fits into a 70mm deep enclosure.

Rated thermal specifications are based on a minimum clearance of 5.1cm

(2in) above and below the equipment and 2.54cm (1in) to the left of the

PNS module.

You may need to allow more space for installation of cables and

connectors than what is required for heat dissipation. To avoid impacting

mechanical reliability and signal quality, cable installation must comply

with the minimum bend radius specified by the cable manufacturer.

Grounding

The VersaMax PROFINET Scanner must have a separate shield ground connection to provide shielding for its two ports.

Attach a wire with a stab-on connector to the grounding terminal on the bottom of the module. Connect a ring terminal on

the other end of the wire to a grounded enclosure. Where the ring terminal contacts a painted enclosure panel, either install

a star lock washer between the terminal and the panel to cut through the paint, or scrape the paint away down to clean,

bare metal to ensure a good contact. Note: The star lock washer method is suitable for a shield ground, but not suitable for

a safety ground.

General Installation Requirements

This product is intended for use with the Product Sub Family system. Its components are considered open

equipment (having live electrical parts that may be accessible to users) and must be installed in an ultimate

enclosure that is manufactured to provide safety. As a minimum, the enclosure shall provide a degree of

protection against solid objects up to 12mm (e.g. fingers). This equates to a NEMA/UL Type 1 enclosure or an

IP20 rating (IEC60529) providing at least a pollution degree 2 environment.

Installation in Hazardous Areas

The following information is for products bearing the UL marking for Hazardous Locations or ATEX marking for

explosive atmospheres:

Features

• Supports redundant power supplies. Use of the second

power supply is optional.

• Supports “hot swap” of a redundant power supply that is de-energized.

• Standard PROFINET alarm and diagnostics reporting.

• Supports configuration using Classless InterDomain

Routing (CIDR) with subnetting and supernetting.

• Each network interface module can be connected into a

daisy-chain/line, star, or ring (redundant media) topology.

• Supports Media Redundancy Protocol (MRP) client mode operation.

• Can be upgraded in the field; supports firmware updates via USB port.

• Provides Maintenance Mode to allow servicing of the

remote node while maintaining network connections.

(Requires firmware version 1.10 or later.)

• Supports Hot-Standby CPU Redundancy using

PROFINET I/O. If the PNS loses communications with

the Primary IO-Controller, it switches to the Secondary

IO-Controller. (Requires firmware version 2.00 or later)

Note: The USB port is for firmware upgrades only. It

is not intended for permanent connection

The VersaMax* PROFINET Scanner (PNS) module interfaces a remote node of VersaMax modules to a PROFINET

IO-Controller. The PROFINET Scanner scans the modules in its node, retrieving input data and providing output data,

and publishes input data on the PROFINET Network at the configured production rate. The PNS manages PROFINET

communication and module configuration between an IO-Controller and modules within the remote node. If network

communications are lost, the PNS manages I/O states according to the individual module configurations.

The PNS is available in two versions to allow you to use the network media that meet the requirements of your application.

IC200PNS001: Two 10/100 Mbps copper interfaces

IC200PNS002: Two 100Mbps Multi-Mode fiber (MMF) ports

The PNS module’s main Remote IO functions include:

• Scanning all the modules within its stick (input and output scan).

• Publishing data onto the PROFINET network to an IO-Controller at a customer-specified production period.

• Receive data from an IO-Controller on the PROFINET network at a customer-specified production period.

• Managing PROFINET communication and module configuration between an IO-Controller and modules within the PNS node.

• Managing the state of the I/O when communications is lost

• Publishing fault information (alarms, diagnostics, etc.) to IO-Controller

Positive or Negative Inputs

Inputs for this module can be either positive or negative inputs (all 16 inputs must be the same

type). Both types of signal produce a logic 1 (true) when the switch is closed. Selection of

positive or negative operation is made by the manner in which the external power supply is

connected to the inputs and to the I/O Terminal Block.

Positive inputs receive current from input devices and supply current to the common or negative

power bus. Input devices are connected between the positive power bus and the input terminals.

Negative inputs provide current to input devices and accept current from the common or

positive power bus. Input devices are connected between the negative power bus and the input

terminal.

A network of resistors and capacitors establishes input thresholds and provides input filtering.

Optoisolators provide isolation between the field inputs and the module’s logic components.

Data from all 16 inputs is placed into a data buffer. The module’s circuit LEDs show the

current states of the 16 inputs in this data buffer.

Parallel±to±seri al converters change input data from the data buffer into the serial format

needed by the Bus Interface Unit.

After checking the Board ID and verifying that the module is receiving appropriate logic power

from the Bus Interface Unit (which is reflected by the state of the module’s Power LED), the Bus

Interface Module then reads the filtered, converted input data.

Host Interface

Intelligent processing for this module is performed by the Bus Interface Unit or elsewhere in

the system. This includes configuring features such as input defaults and fault reporting. The

module has 16 bits (two bytes) of discrete input data. A Bus Interface Unit is required to

provide this input data to the host and/or local processor.

The 24 VDC Positive/Negative Fast Input Module (IC670MDL644) provides a single group of

16 discrete inputs, which may be driven by positive or negative logic.

Power Sources

The module receives power from the Bus Interface Unit to run its own 5±volt logic. An

external 24VDC supply is needed to power the input devices.

LEDs

Individual LEDs (logic side), visible through the transparent portion of the module top,

indicate the on/off status of each input. The PWR LED is on when field and backplane power

are present.
